Locus ceruleus
Definition
The locus ceruleus is a dense cluster of neurons within the dorsorostral pons. This nucleus is the major location of neurons that release norepinephrine throughout the brain, and is responsible for physiological responses to stress and panic[GO]. Bluish region in the superior angle of the fourth ventricle floor, corresponding to melanin-like pigmented nerve cells which lie lateral to the ponto-mesencephalic central gray (griseum centrale). It is also known as nucleus pigmentosus pontis[GAID].
Also known as blue nucleus, caerulean nucleus, locus caeruleus, locus coeruleu, locus coeruleus, Noradrenergic cell group A6, nucleus caeruleus, nucleus of locus caeruleus, nucleus pigmentosus pontis, substantia ferruginea — per UBERON
The Locus ceruleus is a part of the Nervous.
